Application filed November 29, 1918. Serial No. 264,610.

To (ZZZ 10 item it may cancer 1L:

Be it known that I, EDWARD B. UlnarnnL-L, a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented certainnew and "useful Improvements in J ournal-Bearing Supports, of

which the following is a specification.

This invention rel-ates to certain new and useful improvements injournal bearing supports, the peculiarities of which will be hereinafter described and claimed.

The main object of my invention is to provide a journal bearing supportthat is adapted to allow the ready. assembling and t ismounting of therotor shaft of a machine on which my device is used,'and to allow of theminimum amount of machine work.

in the accompanying drawing on which like reference letters indicatecorresponding parts, Figure 1 epresents a half front ele- "ation andhalf sectional elevation of a reducing machine illustrating myimprovements; and Fig. 2 a sectional side view of said improved machinetaken on the line 22 of Fig. 1.

A designates the casing of a reducing machine of any suitable varietyand B the hopper of the same. C designates a horizontal rotor shaftmounted in said casing and having disks D having openings through whichslide hammer rods E on which are mounted stirrup hammers F, constitutinthe rotor of said machine. At suitable points of said shaft outside ofthe casing, a turned down portion forming a shoulder (i, engages a ballbearing of any suitable construction that is held against said shoulderby a jam nut I.

Surrounding and embracing this ball bearing is a housing consisting ofan inner ring J and radiating arms K that are preferably connected by acomplete outer ring L, thus forming a double ring or skeleton housingfor said ball bearing. The said from the middle ring, may be omitted.

This outer member comprises a circular portion, the lower half'ofwhichis conof the ring casin X- This fan casin has ro'ectin A h b M or rigidportion'of the radiating 'nected by a web M with the side of the easingpreferably cast integrally therewith. The upper portion consists of twoconver ing hor. s N separated from the casing as shown in Big. 1, andprovided with a bolt- O or other means by which said horns ma becompressed to such a degree that the said ball-bearing housing, embracedby the circular portion, therein.

Suitable glands T and Q inclosethe outside and inside of said ballbearing respectively, and are clamped against the inner ring J of thehousing by means ofbolts R connecting corresponding lugs S and T of theinner and outer will be clamped securely glands respectively,

by passing through the open spaces outside J and between the radiatingarms K of the skeleton housing.

It will be observed fromthe drawing and the above description, that therotor shaft may be provided with hammers and hammer mounts, and that theball bearings may. be located against the shoulder G in each case, andthe housing engage with and surround the said ball bearing, and that thesaid glands P and Q may likewise be mounted on the shaft and boltedtogether as above .described, and that the whole assembly so fardescribed as constituting the rotor, may

be slipped within said casing A. through a suitable side opening U, andthe housing for each bearing may be clamped in its de sired positionwithin the outer member of the journal bearing support at each side ofthe casing.

Fig. 1 shows a driving pulley V mounted on one end of the rotor shaft,and on the other a fan W within a suitable fan thimbles 3 with openingsfor bolt 4, and said bolts,preferably three in number as shown,entercorresponding registering holes inenlargements or bosses 5 of the webcompressible outer member of the journal bearing support.

The casing X is therefore firmly mounted by said bolts 4; in its properposition with I regard to the fan.

Since the said web M and circular portion of the outer member form apocket around the opening U of the mill casing, I

have providedopenings 6 in the bottom of said web M to allow the escapeof oil or other matter that may enter said pocket.

The opening; U in the mill casing is provided with a split cover 7secured in any suitable manner to the said casing. The web projectslaterally from each side oi the mill casing adjacent to said opening s,so as to locate the clamping member oi? the journal lyearin support asuitable distance away from the side of the casin as required byinsurance bureaus.

The open spaces between the arms K, and particularly the opening 7o atthe top of the skeleton housing, allows of sliding the hai'nmer rod outendwise. as indicated by dashed lines in Fig. 1.

claim:

he combination with a journal beara skeleton housingembracing said innglands on both sides of said bearing a oeari W sl-I-leton housing, boltspassing through and the openings in said skeleton housing andconnectiiiig said gland, and an. outer clamping member supporting saidhousing and its contents.

2. The con'ibinat'ion with an outer compressible member a o a bearing oian interposed housing consisting of an outer ring; engaging saidcompressible member and an inner ring embracing said bearing and havingarms connecting said outer and inner rings and forming a skeletonhousing, substantially as described.

A journal bearing support comprising a laterally projecting Web with aiixed point of attachment, a compiessible bearing support opposite thepoint or attachment, a journal bearing, and a ring within the hearingsupport and surrounding the bearing.

l; in combination with a journal bearing, a support comprising an outercompressible member provided with laterally projecting web said Webhaving a point of attachment opposite said member, and a housingWill'lliil the compressible member and embracing the bearin incombination with a casing, a ournal bearing suppi'irt comprising alaterally projecting sen'iicircular Web secured to the easing and comessible horns opposite said web, means for compressing said horns, ajournal bearing, and a ring Within the bearinn supj'iort and surroundingthe bearing.

in testimony whereoi l have zu'iixed my ,-:i; nature in the presence oi?two Witnesses.
